Description: Iterative Solutions is committed to the mission of developing accurate and efficient software for the simulation of modern communication systems. All software is licensed as open source software under the Lesser GPL. The code is designed to run in matlab, though the compute-intensive portions are written in C and Java. A wide variety of error control codes are supported, including turbo and LDPC codes, and an emphasis is placed on nonbinary modulation formats such as QAM and nonbinary continuous-phase FSK. The software goes beyond the usual error rate analysis by including tools for determining the Shannon capacity of arbitrary modulation formats.-Iterative Solutions is committed to the mission of developing accurate and efficient software for the simulation of modern communication systems.
